Warning Start Of Rant!!!!!!Car (2008 SL550 bought from this dealer “certified pre-owned” with 22K miles) was brought in for B Service (40K miles now). After the service I was told I needed new motor mounts $1100 not covered by warranty
. I scheduled the mounts and got in the car, the steering wheel had a new large scrape, gouge in it
. I brought it back the following week, dropped it off and for the mounts and wheel. When I picked it up there was a humming sound and the steering wheel was not repaired. Brought it back the next day and they told me I needed new rear tires, $1000, why didn't you tell me that at the B Service
? Ordered new tires and came back in to have them, and the steering wheel, installed. I asked how long it was going to take and they told me 2-3 hours. I said "good I have to pick up my wife at 3:15" they said "no problem". I came back at 2:45 and the car was not ready. I asked how long it was going to take and they said they are torqueing the wheels now and it should be done in a few minutes. I used a loaner car to go get my wife and came back to the dealer. The car was still not done
! I asked how long and they said they are washing the car now! I told them I needed to go so don't bother washing it! They said OK I will go get it! At 5:15 they finally brought the car around and had me pay for the tire install. My wife and I got in the car and it was very hot inside like the car had been sitting outside in the sun. I had a meeting 45 minutes away and I was late so I left. While driving to the meeting it kept getting hotter and hotter, the AC was not working! It worked great when I dropped it off
!! I brought it back in and they agreed to look at it no charge and if it is an easy fix they would do it! They let me go back into the shop to see how professional the shop is and watch the repair in person. I stood there for 2.5 hours watching the Service Supervisor plug in and unplug a series of computers 4-5 times and check the AC charge. He finally gave up and said I “your car” needs a new computer because his computer couldn't communicate with mine and he needed to keep the car another day! By now I am very frustrated, so I get a loaner car and go home! Every couple of days I would call and they would say, "we can't figure it out!" They replaced the computer and it still didn't work. I told them to keep the car until the figure it out! About a week goes by and I have to call them again. They say they still can't find the problem. This is getting out of hand. Another two weeks goes by and I call them again to ask what is going on? They say that it has to be the compressor, that’s all that is left and they are not going to pay for it $1200
! I told them to get my car done, it’s been 3 1/2 weeks, and that I am 99% sure it was the compressor
! I tell the manager to do the repair but if it is not the compressor then they need to figure it out and not charge me! He agrees and says I will call you tonight! No call, so the next day I call and they say "it will be done tomorrow, I will call you tonight"! No call, so I show up at the shop on Wednesday and they call the Service Supervisor over and he explains that the high pressure hose liner had collapsed inside and clogged the pipe (My guess is they kinked it when they did the motor mounts.). They then say the car will be done on Friday. I was going out of town so I told them I will pick it up on Monday. On Monday I show up and they tell me that when they went to do it, on Friday (????????), they didn't have the part so they ordered it and it will be done when it comes in! I call them on the following day and they say it will be done tomorrow! They did cover the repair cost and they did finally replace the steering wheel! All in all it worked out but it was a nightmare for me!
So then 6 months later I take my Certified Pre-Owned Mercedes (CPO) to have the A Service and my headlight bulb replaced and the dealer says the headlight housing is leaking and has allowed water in to blow my Bi-Zenon ballast unit. The cost to repair is $2800!!!!!!
I walk out into the shop to look at the light with the mechanic and notice some caulking around the outside of the light housing……WTF is this, I ask. The mechanic says someone must have tried to repair it before. I tell him the only people to touch this car is the dealer where I purchased it “CPO”! It is now 1000 miles out of warranty and they refuse to cover it! I am tired of fighting with Mercedes
I ended up purchasing a used headlight housing and putting in myself for $300!
I have lost confidence that the mechanics of today have the basic diagnostic/repair skills necessary to objectively look at a problem from a mechanical perspective, and they put too much faith in computer diagnostics!
OK, sorry for the rant but this is a car that cost $115,000 when it was new and only has 40k miles!!!!!!!!!
